Hello,

I want to view and if possible convert some dicom images which i 
received on a cd from a radiologist. The cd is supposed to work in a 
plug-and-play fashion, but it doesn't work.

When using a hex editor to view the image files, the first bytes show a 
string "GE Medical Systems / DICOM Part 10 file". Each image is located 
in a subdirectory within the DICOMDAT directory. There is as well a 
DICOMDIR file located in the root directory. The first bytes within the 
dicomdir file show a string "GE Medical Systems / DICOM Part 10 file / 
CENTRICITY 001471".

Since the shipped viewer does not work, I tried a number of other 
programmes to access the files, without any success. The image files and 
the dicomdir filed are always reported as invalid. In the dicomdir file 
there are strings probably containing the radiologists' software: 
Applicare/Radworks.

Is there a way to view the files without the buggy GE CENTRICITY viewer?

Thanks for any hints,
perry

You could use the command line tools from GDCM to check if those files
are actually DICOM files. The command line is gdcminfo:

http://gdcm.sourceforge.net/html/gdcminfo.html

If they are, you could use something like IrfanView + DICOM plugin to
view them (or any other viewer).

Dear Perry,

If you are still facing the problem, please share one of the
problematic image.

Dear Alvin,

I just tested the cd on a different computer and luckily there it 
worked. It seems that the images on the cd are generated with some 
non-standard compression technique. The viewer shipped with the cd 
allows to export the image as dicom, jpg, tiff and bmp. When exporting 
to dicom, the resulting file is much larger than the corresponding input 
file. This output file seems to be standard, I was able to view it with 
xnview.

Thank you and regards
Perry
